Interesting stuff IMO, but I'd be more interested in what some smarter people think of it and its usefulness. It certainly seems like the best way to get the most bang from your drivers if you are designing them. The new large PE fullrangers also have impressive performance on all fronts.

Dan, thanks for trying to get discussion going here. I'll post the recent news I posted on diyma & techtalk. Not sure if anyone here is paying attention or cares to so I probably won't be back here to continue the update. That said... here you go...

Understandable, and so far that's not stopped a lot of you guys from venturing over there to view the data.

I've been working to provide FR/HD/CSD data to everyone in addition to the small and large signal analysis I achieve through the Klippel. In fact, 2 days ago, I purchased the omnimic in order to do so. Since, then, though I've gotten some kickass news!...

As mentioned in the other Klippel Updates thread, I have been speaking with the folks @ Klippel in regards to obtaining some modules and hardware to help us further our cause. I heard back today and this is what was said:

We thank you for your effort and appreciate your enthusiasm in providing KLIPPEL data to the community! We are going to loan to DIY forum the other modules of KLIPPEL R&D SYSTEM free of charge for the period of time you are using them actively. As you know, you can measure without a laser, but it is more convenient using the laser in LPM measurements. So we recommend purchase of a laser and microphone. We will give you an extra discount to help DIY a bit. Please find below some details:

1. Modules

We are going to give you 3 month license keys for all modules and latest software release. When they run out, you can contact me to inform me, that you are still working actively with the system. Then we send you keys for next 3 month and so on. If nobody at DIY have time or interest to measure, it is “sleeping” and you can contact me, when you want to start again. During “sleeping time” the LSI module you purchased before (Release 200) will work only. We cannot lend you the modules which requires additional equipment as SPM, MPM and SCN.

2. Laser + Microphone

If you test woofers only, laser ANR1282 (+controller) is recommended. With more expensive laser H52 you can test micro-speakers and tweeters also, but maximal displacement is +-10mm. We offer various types of microphone. The less expensive MI17 is okay in most cases. Please check attached specification and price list.

So as a minimum you should order:

· Laser sensor ANR1282 – *** EUR

· Laser controller ANR5132 – *** EUR

· MI 17 Microphone Set – *** EUR

Total: *** EUR – discount% = *** EUR

Please let me know what you think.

Best regards

So, I'm still not 100% we need the Laser and it's VERY expensive. I left the $$$ amount out, but suffice it to say, it's a hefty investment. However, we need the mic. Absolutely have to have the mic to do HD and FR testing.

Depending on what Ant says regarding this, we may just be on the leading edge of all measurements from here on out. To say I'm excited is a huge understatement.

Auralization:Auralization (AUR)
(this will allow me to extract various distortion components so you can hear the influence in sound; this will be an awesome tool)

I'm sure there is more behind the doors that have been opened for us by the fine folks at Klippel. I can't wait to see where this goes!

We just need to decide if the purchase of the laser will be beneficial to us. Like I said, it's a HUGE investment for Ant and at the end of the day, he needs to be able to know that it will ultimately pay off. FWIW, personally, I couldn't fund it.

This means that the rate I've been testing will be slowed a good bit, though, simply because there's now more to test. Be on the lookout for these upgrades. I'll keep this thread updated with information as we move ahead.

Just wanted to let you all know and this certainly needed it's own thread.

Be prepared for the full gamut of testing. It will all be posted on DIYMA, still, but I will happily provide a link to every test I do from hereon. I encourage you all to go ahead and sign up so you can view the data as it's posted in the future. Obviously the site owner needs to get some reimbursement for his purchase so the data must stay there. I'm sure you can all understand. Especially when you realize the hardware costs are in the thousands of dollars and none of us are footing the bill.
